You can choose to add the alias, cancel, or, if you know you’ll never want to add an alias, tell PStill never to ask. If you choose OK, PStill will create an alias of itself with the name “Repurpose with PStill”.

You can also add folders and aliases to folders to the PDF Services folder. This allows you to save PDF directly from the Print dialog to a watched folder for further automatic processing.

Once you’ve added items to the PDF Services folder, all Print dialogs will show a PDF button. Clicking on the button will display a menu of options, including Repurpose with PStill.
